Most people prefer to have “sa”  account as the database owner, primary reason being sa login cannot be removed/deleted unlike any user account or service account and so the databases will never end-up in an orphaned stage.

I came-up with the below method to change the ownership to sa on all the 40 databases in our environment recently.

Step 1: Check the databases that does not have sa account as the owner

SELECT name AS DBName, suser_sname(owner_sid) AS DBOwner  
FROM sys.databases
WHERE suser_sname(owner_sid) <> 'sa'
 

Step 2: Generate the scripts to make sa account as owner for all the databases

SELECT 'ALTER AUTHORIZATION ON DATABASE::' + QUOTENAME(name) + ' TO [sa];'
from sys.databases
where name not in ('master', 'model', 'tempdb', 'msdb')
AND suser_sname(owner_sid) <> 'sa'
 

Step 3: Execute the result set from step 2 above to change the ownership to sa

--Sample result set from step2 above
ALTER AUTHORIZATION ON DATABASE::[AdventureWorksLT2012] TO [sa];
ALTER AUTHORIZATION ON DATABASE::[Northwind] TO [sa];
ALTER AUTHORIZATION ON DATABASE::[Pubs] TO [sa];
